Is this a profitable spot for a steal?

[roggles]

As the title implies, I wonder if you think this was a +EV place to steal. The table is quite nitty, and every time I've raised preflop and cbet on the flop people have folded. I'm pretty sure everyone would fold a bare ace.

i never check twice, so the turn is an easy pot for me - if anyone has the straight they are betting the turn 100% on a nitty table, i dont mind the flop check on this flop 4 way

[alavet]

sure, take it

What actually happened was that UTG called and had 55. It was a totally wtf moment for me. I guess I need to learn to distinguish between weak and tight.

id just check here 3 other guys someone easily could be trying to show down a 7 as cheap as possible. 55 is funny.
